改了什么

  • governance/transitions.yaml:T6 guard sender_role=='agent'owner∪agent(对齐 T1/T5/T7-T9)
  • .github/workflows/conductor.ymlcheck_triple_survived 在无 dispatch 载荷时(标签路径)从本卡 survived 评论机械提取 run_id

为什么

W4-C1 上线的 T6 自部署即不可达(IR-0006 W1 实走发现,issue #402 卡在 redteam):

  • workflow_run 未注册触发;repository_dispatch 无法定位 issue 且 etype 白名单永不匹配;
  • label 路径被 agent-only guard 拒绝——唯一 agent 身份=cloudbrid-agent App,无组件替 PM 打标签;
  • 即便 App 打标签,run_id 只认 dispatch 载荷 → 必然 DENIED"缺少审计 run ID"。
    PLAYBOOK §3 的 PM 主路径(打 adversary:survived → T6)自上线即被自己的 guard 拒绝。
    证据闸门语义不变:三元组(卡 ID+specVersion+审计 run ID)仍由 conductor 机械校验,fail-closed。

怎么验证

风险 / 回滚

guard 放宽仅影响"谁可触发",判定仍机械;回滚=revert 两文件。conductor.yml 同字节
部署面(8 产品仓+template-service)后续同步,期间产品仓 IR 走旧字节(T6 不可达,
非回归)。

Refs: ADR-0085(状态机补洞先例)、ADR-0079(T6 原设计 W4-C1)

Summary by CodeRabbit

  • 功能改进

    • 完善 T6 存活记录校验:缺少运行标识时,可从相关评论中自动提取。
    • 支持由所有者或代理触发 T6 转移,同时保留标签和审计校验要求。
  • 问题修复

    • 当无法提取运行标识时继续拒绝处理,确保校验安全可靠。

W4-C1 上线的 T6(redteam→wave-planned)自部署即不可达(IR-0006 W1 实走发现):
- workflow_run 未注册触发;repository_dispatch 无法定位 issue(github.event.issue 空)
  且 etype 白名单永不匹配;label 路径被 sender_role=='agent' guard 拒绝
  (唯一 agent 身份=cloudbrid-agent App,无任何组件替 PM 打该标签)。
- 即便 App 打标签,check_triple_survived 的 run_id 只认 dispatch 载荷→标签路径
  必然 DENIED"缺少审计 run ID"。

修复(证据闸门语义不变,fail-closed 不变):
- transitions.yaml T6 guard 对齐 T1/T5/T7-T9 的 owner∪agent——PLAYBOOK §3
  "打 adversary:survived 标签→T6"的 PM 主路径恢复可用;
- conductor 路由 check_triple_survived:run_id 缺载荷时从本卡 survived 评论机械提取
  (须含 verdict=survived 且带 run_id 键,与跨卡复用检查同源同则)。

三元组其余两项(卡 ID、specVersion)与跨卡复用检查不动。conductor.yml
同字节部署面(.github+8 产品仓+template-service)另行同步跟进。

修复 T6 owner 可达性与标签路径 run_id 回退

🐞 Bug fix 🕐 10-20 Minutes

Grey Divider

AI Description

• 恢复 owner 与 agent 触发 T6 的可达路径。
• 标签事件缺少载荷时,从 survived 评论提取审计 run_id。
• 保留三元组校验与缺失证据时的 fail-closed 行为。

High-Level Assessment

The following are alternative approaches to this PR:

1. 修复 repository_dispatch 契约
  • ➕ 保持 T6 完全由 agent 驱动
  • ➕ run_id 可由生产者直接传递,避免评论扫描
  • ➖ 需要同时修改 adversary 生产者、issue 定位载荷和事件白名单
  • ➖ 跨多个部署仓同步,修复范围与上线风险更大
2. 新增 workflow_run 触发
  • ➕ 可直接关联 adversary 工作流运行
  • ➕ 减少对评论格式的依赖
  • ➖ 当前工作流未注册该触发面
  • ➖ 需要解决跨仓 issue 映射及 workflow_run 安全约束

Recommendation: 当前补丁是恢复 PLAYBOOK 既定 PM 标签主路径的最小安全修复:只放宽触发身份,不放宽证据条件,并在缺少 dispatch 载荷时复用 survived 评论格式补齐 run_id。后续可单独完善自动 dispatch 契约,但不应阻塞本次 T6 可达性修复。

Merge Risk: 🟠 High · up to 48773

The PR broadens T6 triggering and adds a comment-based run_id fallback. As written, stale or fabricated issue-comment text could satisfy the audit requirement and permit a state transition without a genuine adversary run, so merge should wait for authoritative evidence validation; the missing pagination can also reject valid runs.

Action required

1. Untrusted comments bypass gate 🐞 Bug ⛨ Security
Description
The fallback accepts any comment containing a survived substring and a run-like token, then the
existing check merely rediscovers that same token on the same issue; it never verifies the comment
author, the Actions run, or any binding to card_id, specVersion, or the current lifecycle. Thus
a stale or user-authored comment such as adversary:survived run_id=fake can satisfy T6 once an
owner applies the transition label, despite the transition contract forbidding historical/cross-card
evidence.

●● Moderate

Security concern is plausible, but recent conductor substring-validation findings were rejected; no
decisive matching spoofing precedent.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence
The added lines accept substring text and extract only run_id; the downstream code builds
card/spec fields independently but validates the ID only by scanning the same issue comments. The
transition's own documented contract explicitly requires card/spec/current-lifecycle binding, while
the relay demonstrates that authoritative verification normally checks run success, workflow
identity, verdict, and head SHA.

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The label-path fallback treats arbitrary issue-comment text as a valid adversary audit record, without proving that the run exists, succeeded, produced a survived verdict, or belongs to this card/spec/current lifecycle.

## Issue Context
T6 is documented as requiring a mechanically verified card ID + specVersion + audit run ID triple and rejecting historical/cross-card reuse. The fallback and subsequent check currently compare only an extracted token against the same comments that supplied it.

## Fix Focus Areas
- .github/workflows/conductor.yml[377-429]
- governance/transitions.yaml[69-92]

Require a structured record from a trusted producer, verify its author/provenance, and query the Actions API (or another authoritative audit store) to confirm the run, survived result, card, spec version, and current lifecycle binding before allowing T6.

2. Comment pagination rejects evidence 🐞 Bug ☼ Reliability
Description
Both fallback scans call the comments endpoint once without pagination, so GitHub returns only the
first 30 comments in ascending order and a valid survived record after comment 30 is invisible. On
such issues the label path is denied for missing run_id, while an old survived-looking record in
the first page may be selected instead of the current one.

●●● Strong

Recent accepted precedent specifically requires paginating GitHub API listings to prevent incomplete

ⓘ Recommendations generated based on similar findings in past PRs

Evidence
The API helper performs one request and returns only that response body, while the new fallback uses
the bare comments endpoint and breaks on its first match. GitHub's official endpoint documentation
states that comments are ascending by ID and defaults are per_page=30 and page=1.

.github/workflows/conductor.yml[122-134]
.github/workflows/conductor.yml[398-428]
🌐 GitHub documents that issue comments are ordered by ascending ID and that the endpoint defaults to 30 results on page 1.

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The new fallback reads only the default first page of issue comments, making valid evidence unreachable on issues with more than 30 comments.

## Issue Context
GitHub orders issue comments by ascending ID and defaults to 30 results on page 1. The local `api` helper performs a single request and does not follow pagination links.

## Fix Focus Areas
- .github/workflows/conductor.yml[122-134]
- .github/workflows/conductor.yml[398-428]

Fetch all comment pages (or query a bounded authoritative record directly), avoid duplicate comment requests, and select the evidence explicitly bound to the current lifecycle rather than the first historical match.

GitHub REST API list issue comments default pagination per_page page Link header

💡 Result:

For the GitHub REST API endpoint to list issue comments, the default pagination settings are as follows: - per_page: The default number of results returned per page is 30, with a maximum limit of 100 [1][2][3]. - page: The default page number is 1 [1][2][3]. When an API response is paginated, GitHub includes a Link header in the HTTP response [4][5]. This header provides URLs that you can use to navigate between pages of results [5][6]. It contains links for the following relations [5][6]: - rel="prev": The URL for the previous page. - rel="next": The URL for the next page. - rel="last": The URL for the final page of results. - rel="first": The URL for the first page of results. If an endpoint does not support pagination, or if all results fit on a single page, the Link header is omitted from the response [5][7].

为 T6 的 issue comments 查询实现分页。

check_triple_survived 请求 /repos/{REPO}/issues/{issue_number}/comments 时未设置分页参数。GitHub 默认每页返回 30 条;api 也未保留 Link 响应头。当符合解析规则的 survived 评论位于后续页面时,T6 会找不到 run_id 并错误地 fail-closed。后续跨卡复用检查同样只读取第一页,也可能错误拒绝合法的 run_id。请读取全部分页结果,并增加跨页测试。
